Unity’s Mono problem: Why your C# code runs slower than it should
Execution of C# code in Unity’s Mono runtime is slow by today’s standards, much slower than you might expect! Our game runs 2-3x faster on modern .NET compared to Unity’s Mono, and in a few small benchmarks I measured speedups of up to 15x. I’ve spent some time investigating what’s going on and in this […]
Software engineers should be a little bit cynical
A lot of my readers call me a cynic when I say things like “you should do things that make your manager happy” or “big tech companies get to decide what projects you work on”. Alex Wennerberg put the “Sean Goedecke is a cynic” case well in his post Software Engineers Are Not Politicians. Here […]

No it’s not a Battleship
This week has seen the announcement by the Trump Administration that they are going to be building ”battleships”, a subject that is well within my beat, so I figured I would take the time to start by saying that these are nothing of the sort. Defining the battleship is slightly tricky, but the best version […]

Tell HN: Google ignores English searches and forces localized results
Google Search change in a way that I can’t seem to opt out of. I’m based in a non-English-speaking country, but I regularly search in English, especially for technical topics. My Google account, my laptop, my phone, my interface language, and preferences are all set to English; only my physical location and payment methods are […]

Beyond transporting messages, SCTP can also set up a connection between users. On a deeper level, SCTP includes […]
